An arcuate component includes, a flexible outer board, a flexible inner board and both a first and a second plurality of arcuate tiles. Tongue and groove tracks formed along opposite longitudinal edges of the outer and inner boards lock with mating arcuate tongue-and-groove edges of the arcuate tiles which respectively span between the outer and inner boards. The arcuate tiles also preferably include at least one tongue-and-groove that spans between the outer and inner boards and that mates and locks with a tongue-and-groove formed on an immediately adjacent tile. A series of slots cut across the outer and inner boards between their longitudinal edges increases their flexibility. The mated arcuate tiles constrain the outer and inner boards into an arcuate shape. Alternatively, tongue-and-groove tracks formed along opposite longitudinal edges of a plurality of boards mate to form a cylindrically shaped arcuate architectural component such as a column. A series of slots cut along boards forming a column parallel to the board's longitudinal edges increase their flexibility.
